AMD Ryzen 7 7840U — Benchmarks & Specs

Bottom line: how fast is the AMD Ryzen 7 7840U?

For local LLM inference it generates 5.6 tokens/sec running llama3:8b under ollama, per Framework Community. In PassMark CPU Mark it scores 24,386 pts, per PassMark. Across all its cores it scores 13,981 points in Cinebench R23 multi, per Notebookcheck.

Every figure above is a row in the tables below, and each row links out to the review or public benchmark database the number was taken from. SpecPicks aggregates published measurements; it does not report first-party benchmark runs.

The AMD Ryzen 7 7840U is a processor from the Zen 4 family from AMD. Data on this page draws on 8 synthetic benchmark results, 2 community AI inference reports, 5 measured game frame-rate results, compiled from Technetbook, Framework Community, Notebookcheck, Geekbench Browser, PassMark; each table row links to its source. Read this page when shopping the AMD Ryzen 7 7840U, comparing it against other processors in your build, or sizing it for a specific workload (gaming at 1080p/1440p/4K, synthetic benchmark scores, or local LLM inference).

Gaming Performance (measured FPS)

Average and 1% low frame rates by game, resolution, and quality preset. Bars are scaled against the fastest result on this page.

Measured gaming frame rates for the AMD Ryzen 7 7840U by game, resolution, and quality preset. “1% low” is the frame-time floor that determines perceived smoothness. A CPU’s frame rate depends on the graphics card it was tested with, named in the Test GPU column when the source records it. Each row links to its original review or benchmark database.

AI Inference Performance

Tokens per second under each model + quantization. Higher = faster generation. Bars compare runs across the same model.

Local LLM inference throughput on the AMD Ryzen 7 7840U, in generated tokens per second for a single request (one user's generation speed). Higher is better; each row links to the community report or benchmark database it came from.
Model Quantization Relative Tokens/sec VRAM used Source
llama2:7b — ollama 12.0 tok/s — Framework Community 2024-04-01
llama3:8b — ollama 5.6 tok/s — Framework Community 2024-06-01

Synthetic Benchmarks

Higher is better. Bars are scaled within each benchmark family (multi-thread, single-thread, etc.) so you can compare like-with-like at a glance.

Synthetic benchmark scores for the AMD Ryzen 7 7840U — higher is better. Each row links to the public database the number was taken from.
